Call Stack
Stores active function frames, return locations, and local execution state
Why learn Call Stack?
It implements nested calls and structured returns efficiently
The problem it solves
It tracks unfinished function invocations in execution order
Where it came from
Call Stack is a programming language and runtime concept that stores active function frames, return locations, and local execution state. Its guarantees and tradeoffs depend on the concrete implementation and operating context.
